Most of the aluminum (铝) cans in the United States are made with recycled aluminum. This is one way to recycle resources.

Aluminum and steel cans, cardboard, glass, newspapers and plastic bottles are all recyclable. These items can be made into new products including cans that hold food and drinks, the steel used to build skyscrapers and school buses and even playground equipment! It’s up to you to protect the environment! Keeping our planet clean and safe is everyone’s duty. If you make a habit of reducing, reusing and recycling, you can make the world a better place.
